Symposium "Tektonik, Struktur- und Kristallingeologie" %D 2006 %R 10.23689/fidgeo-1920 %I Universitätsverlag Göttingen %X For many years it has been known that near surface isotherms are influenced by the topography (Lees 1910). Recently, a number of studies were pursued to quantify the effect of topography on low temperature isotherms (e.g. Stüwe et al. 1994, Mancktelow & Grasemann 1997). The magnitude of perturbation depends on several parameters: exhumation rate, geothermal gradient, wavelength and amplitude of topography, and finally by the age of surface relief change (Braun 2002). %U http://hdl.handle.net/11858/00-1735-0000-0001-3433-5 %~ FID GEO-LEO e-docs
